Extruded bi-metal fin tubes

BI-METAL FIN TUBES:

gewalzte Rippenrohre - Bi-Metall

are produced by a roll forming process similar to thread rolling. we roll form an aluminium tube onto any selected type of inner tube. Due to the roll forming process we achieve a spiral aluminium finning having a very strong contact to the inner tube. Due to work hardening at this rolling process the finning gets very rigid and can withstand remarkable mechanical stress. So it is possible to clean the tube bundle without deforming or flattening the finning. Extruded bi-metal fin tubes are extremely corrosion resistant because the inner tube is completely covered by the finning material having no splits.

MONO-METAL FIN TUBES:

mono- metal fin tubes are produced by a roll forming process similar to thread rolling. Here we can use any tube material like copper, copper alloys, aluminium and its alloys
